AirLogix® optimizes energy efficiency, increases reliability, and promotes system visibility through data and integration. Each controller we build is custom, engineered specifically for each application, and done with nearly unlimited capabilities.

What sets AirLogix® apart from any other controller is our unique control algorithms and methodology. Through decades of experience, we’ve developed a product that completely automates and optimizes the compressor. To achieve this, we continuously monitor and adjust for real-time major influences on performance like changes in ambient air temperature, pressure, and various rate-of-change functions.

AirLogix® is incredibly user-friendly but also open-source which means it consists of no Case Controls proprietary hardware. The HMI home screen provides an easy to understand, detailed machine information at a glance. Additional screens provide the ability to create and tailor personalized views to display the information that is of the greatest interest. We give you the tools to add, name, scale, configure I/O, tune PID loops, manual valve control, and so much more.

Unlock the true potential of any centrifugal air compressor with AirLogix®.


Features & Benefits


Software Back-Up Copies

Back-up copies of the specific buildout are provided on memory cards and shipped installed in the PLC and HMI for insurance in case of hardware failures.

Ethernet/IP Communication

Native communication protocol is Ethernet/IP. Other protocols are optional for connection to any third-party system.

Plug and Play Retrokit

Tried and true control upgrades for OEM legacy controllers which make for fast and easy installation. By utilizing the existing enclosure, our Retrokits are designed to fit with minimal compressor downtime.

AirLogix® compatible with 3PX-Backbone™

This feature enables and permits the electronic integration of Case Controllers with numerous third-party controllers.

Dynamic Throttle Limit (DTL™)

Case Controls unique proprietary control algorithm which compensates for changes in ambient air temperature fluctuations. This provides for greater turn-down in centrifugal compressors resulting in improved energy savings and superior surge control protection.
Full Control HMI Functionality

Human machine interface (HMI) allows for the complete configuration, tuning, troubleshooting, and operation of the compressor. Complete with detailed information, data trending, and graphics for easy to use and understand control at the fingertips.

Industry Standard Automation – Allen-Bradley PLCs and HMIs

Built on the Allen-Bradley industrial control solutions by Rockwell Automation, Case Controls uses ZERO proprietary parts. This means customers are free to select from a worldwide distribution network and multiple vendors for replacement hardware components and product support.

Documentation & Diagrams

Complete documentation sets including wiring diagrams, parts lists, and user-manuals, which thoroughly address set-up, tuning, troubleshooting and operations.
